I only ship mon through wed. I wouldn't personally buy from anyone who didn't. If they are packing the animal appropriately, it doesn't need to be in the 80's to ship. They would just have to use a proper animal heat pack and place it accordingly.

I shipped one out a couple weeks ago and because it was going to be in the 50's over night both here, and at the destination, I added an activated heat pack but put it off to one side and covered it with a little newspaper so the snake wouldn't get too warm in the daytime temperatures.

The shipper should adjust what they do and what they use depending on the weather. Never be afraid to ask the seller for details on their shipping and packing methods.
